Mysterious Underwater 'Crop Circles' Discovered Off the Coast of Japan

According to the National Oceanic and Atmospheric Administration less than five percent of the world’s oceans have been explored, meaning that 95% of what lies deep underwater on Earth has yet to be seen by human eyes.

One person who has dedicated his life to uncovering the mysteries of the deep is Japanese photographer Yoji Ookata who obtained his scuba license at the age of 21 and has since spent the last 50 years exploring and documenting his discoveries off the coast of Japan. Recently while on a dive near Amami Oshima at the southern tip of the country, Ookata spotted something he had never encountered before: rippling geometric sand patterns nearly six feet in diameter almost 80 feet below sea level. He soon returned with colleagues and a television crew from the nature program NHK to document the origins what he dubbed the “mystery circle.”
